It's difficult for me to do this without the help of the builder lo.

But you may be going up in the tree too far.

The buttons are not actual pages, but buttons only. So they are not really a level.

So you may try Parent.Market instead of Parent.Parent.Market.

Also, you only had the command listed once in this file, and maybe that was the problem.

try this one.
I duplicated the line Parent.Market.ComboItemType.SelectedItemIndex=2

You can also try throwing in the Extra Parent which I removed.
